This diagram illustrates how multiple elements contribute to the total VSWR of a typical W/G subassembly.  In the above case, elements of interest such as: Cast Miters at figures A, C, D, and E, and a Flex W/G section at Fig. B, are shown with their corresponding contributing VSWR values.  By entering the values given above into the VSWR calculator, we see that the probable assembly-chain VSWR of: 1.05 + 1.08 + 1.05 + 1.05 + 1.05 = 1.13
